I To all whom 'it may concern:

Be it known that I, JAMES K. P. PINE, a citizen of the United States,and a resident of Troy, in the county of Rensselaer and State of NewYork, have invented. certain new and useful Improvements in Machinesvfor Bending Collars and the Like, of which the following is aspecification.

My invention relates to a machine for bending starched articles, andmore particularly a machine for folding or bending the corner of acollar, cuff or similar article. Mens linen collars of the wing orwingpoint form are ordinarily laundried flat, and the win or corneris'afterward bent outward. n account of the stiffening of the collar bythe starch therein, the material is very likely to crack along the lineof fold.

My device is a novel machine for bending starched articles such as wingsof collars and it also provides novel means for dampening the collar toa sufficient extent before or as it is folded, and means for adjustmentso that collars of different sizes and patterns may be folded on thesame machine.

In the drawings, Figure 1 is a plan view of a machine embodying myinvention. Figs. 2 and 3 are side elevations o1 the opposite sidesthereof. Fig. 4 is a partial end elevation showing the fold producingdevice. F ig. 5 is an end elevation of the part shown in Fig. 4. Figs.6, 7 and 8 are partial end elevations on an enlarged scale of thefold-producing portion of the device,

showing its different positions. Fig. 9 is a partial end elevationshowing the support for the article to be folded. Fig. 10 is a planvview `of the same. Fig. 11 is a similar Fig. 12 is a partial detail planView of a heating device. Fig. 13 is a partial diagrammatic plan viewshowing the gage portion of the device.

I will rst describe a particular form of machine constituting oneembodiment of my invention and will afterward point out the novelfeatures in the claims.

4Broadly speakingmy machine for producing a bend in starched fabricarticles contemplates first a member having an edge over which thearticle may be bent, said edge' corresponding withgthe line of the bend.Second, a bending device for coper- `ating with said edged member uponboth sides of the edge of the latter, preferably comprising for examplea pair of rollers, one of which may pass on one side and the other onthe other side of the edge when an article is being bent. Third, amechanism for producing relative movement between said first and secondelements so that on their relative approach the fabric may be bent aboutthe edged member and on thc separation or relative movement from eachother, the article maybe released to permit its removal and theinsertion of a new one; this mechanism acting preferably upon thebending device only so as to cause it to approach and recede from theedged member. In connection with the above principal elements, I alsopreferably provide heating means such as passages for steam circulationby which the edged member or the bending device may be maintained inhighly heated condition, which would be important in bending the wingsof wing collars. Also an apparatus by which the starch of the starchedarticle may be moistened so as to break the starch along the apex of theedged member previously to its bending; and the action thereof should besuch that the moistening ceases as or immediately before the bendingtakes place in order that the bending may be in the nature of an ironingaction and leave the finished article without any moisture. To this endmy invention in its preferred form contemplates also such an apparatusthat the starch breaking medium or steam can be intermittently appliedalong the edge to be bent, and this intermittent action 1s securedautomatically in the specific form of machine illustrated in thedrawings, through the agency of appropriate mechanical connections.Other preferred features or details will appear in the followingdetailed description, which as previously stated discloses but one ofmany forms which my improvements may assume.

1 designates the base of the machine, from which rise standards 11, 12,13 and 14. The standards 1l are provided with suitable bearings 15 for ashaft 16, on which is a pulley 17 connected by a belt 18 to any sourceof power. Mounted on the shaft 16 is a cam wheel 2, on one side of Whichis an approximately triangular cam groove 21 and a cam 22, (see Fig. 2),and on the other side of which is a cam groove 23 and a cam surface 24,to be hereafter described, (see Fig. 3). Suitably supported on the base1 is a support 3 for the article to be folded. This is shown as a hollowchamber flared at its top and having an edge 31 formed with a slot 32(see Fig. 10), or in the modified form shown in Fig. 11, formed with. aplurality of apertures 33. To the chamber of the support 3 leads a pipe34 which is connected with a supply of steam or other suitable dampeningmedium. In the pipe 34 `(see Fig. 3), is a valve 35 having a handlelever 36 pivotally secured to a block 37, which is apertured to slidefreely on a rod 33. On the rod 38 are set collars 39, one at each sideof the block 37 .Y One end of the rod 38 is pivoted at 310 to a lever311 pivoted at 312 to the standard 14. vAt the other end of the lever311 is a pin 313 which may advantageously be provided with a roller, andwhich moves on the cam surface 24 on the cam wheel 2. As shown, thesupport 3 is provided at its upper corners with upwardly extendinglugs314, (see Fig. 9). Pivoted on the standard 13 is a lever `4, at. one endof which is a roller pin 41 ruiming in the cam groove 23, Fig. 3. Theother end of the lever 4 is connected by a link 42 to a lever 43, theend 44 of which is bifurcated to pass over and be guided by the shaft16, Fig. 2. YOn the lever 43 is a roller pin 45 engaging in the camgroove 21. At the other end of the lever 43 is a socket 46, in which isadjustably mounted by means of a pin 51 a yoke 5, to which is pivoted across bar 52, Fig. 4. A Hat spring 531 is shown as secured on the upperside of the yoke 5, and as having its free squared end bearing on theupper face of the bar 52. At the ends of the bar 52 (see Figs. 6, 7 and8), are flat springs 53 having at their free ends lugs 54 formingbearings for the parallel shaft-s 55 of two rollers 56, Fig. 5. The endsof the shafts 55 are connected by links 57 pivoted together by a shaft58. Ratchet wheels 59 secured at the end of each of the shafts 55 engagewith oppositely disposed dogs 510 pivoted on the spring straps 53 andmaintained in engagement by flat springs 511. Pvoted on the standard 12isa lever 6, one end of which is provided with a roller pin 61 adaptedto coperate with the cam 22 on the cam wheel 2. At the other end of thelever 6 is a forked portion 62, which passes between the strap springs53 and is adapted to bear against the pivot shaft 58. This forkedportion of the lever or bar 6 is beyond the point where said bar Vispivoted, and as seen in Fig. 1 is preferably made with two branches byreason of the bar being forked at this point. The forked bar portion 62is extended as explained between the springs 53 and in such a positionthat when moved downwardly the branches thereof will press the shaft 58,causing the links 57 to act as a toggle to separate the rollers 56 andrelease the collar. The forked portion 62 is given such length that whenthe rollers are shifted from the idle position of Figs. 1, 2 and 3 toaposition above the support 3, the portion 62 will still be in properrelation for actuating the links 57 to separate the rollers. Passingthrough suitable apertures in the standard 12 are gage rods 7, the freeends 71 of which are 11p-turned, the rods 7 extending at each side ofthe support 3. The rods 7 are made longitudinally adjust-able in thestandard 12 by set screws 72. Connected with a gas supply is a ,pipe 8,the end 81 of which is provided with gas emission apertures 82 (see Fig.12), and is placed as shown in Figs. 2 and 3 of the drawings for apurpose to be hereafter described.

The operation of my device is as follows The collar 9 or other articleto be folded is placed on the edge 31 of the support 3, the upper edgeof the body of the collar bearing against the upturned end 71 of thegage rod 7, and the lug 314 on the support 3 engaging in the corner ofthe collar between the nose 91 and the wing 92. It is obvious that thegages 7 may be so set as to bend a corner 92 of any desired size andshape. By providing the gages 7 and lugs 314 in duplicate, both cornersof the collar may be bent, as indicated in Fig. 13. The machine standingin the position indicated in Figs. 1, 2 and 3 of the drawings, is thenstarted, when the levers 4 and 43 act to move the rollers 56 toward theedge 31 of the support 3, and then downward over the edge and over thecollar 9, as shown in Fig. 6. The further movement of the machine raisesthe rollers 6 off the support 3 with the collar inclosed between them,as shown in Fig. 7. Vhen the shaft 58 rises to the position shown inFig. 7 it is forced by the quick downward movement of the forked end 62of the lever 6 so as to spread the rollers apart (see Fig. 8). Thisreleases the collar and permits the operator to remove it. The cams onthe cam wheel 2 are so timed that immediately before the bending actionof the rollers is applied to the collar, the valve 35 is opened and thenimmediately cut off so as to permit a small quantity of steam to passout of the apertures 32 or 33 to moisten the collar so as to prevent itscracking during the folding operation. By properly adjusting the setcollars 39, the time of the steam admission and cut-olf may be regulatedas desired, but practically the steam should be cut off as the bendingtakes place, that is, not later than the actual bending, since thearticle is to be left dry. By this I mean it may be before the bendingtakes place if it be immediately before, not long enough before topermit the collar to dry or the starch to stiffen before the bending.When the rollers 56 are moved away from the support 3 and returned tothe position shown in Figs. 1, 2 and 3 of the drawings, they are locatedimmediately lover the gas apertures 82 in the pipe end 81, which driesthe rollers yof any superfluous moisture. By reason of the pivotalmotion of the bar 52 on the yoke 5, which motion is controlled andlimited by the spring 531, any slight adjustment of the downwardmovement of the rollers over the collar is made bythe support 3. This isadvantageous particularly when the wing of the collar or other articleto be folded is of fewer plies than the body of the collar.

It is `obvious that many mechanical changes may be made in my devicewithout departing from my invention, and that parts of the ydevice maybe used without others.
